We're bringing the big stroller, one of those backpack leashes (don't judge, he's not a huge fan of the stroller), plenty of snacks and water. He'll be coated in sunblock and bug spray. We'll take extra changes of clothes. I'll take him back to the close-by hotel for naptime (12 - 2 pm). We'll be there with plenty of additional family -- five other folks, in fact.
Any advice you have for me?
